Abstract
The utility model relates to an energy-saving steam boiler and belongs to the technical field of boilers. The energy-saving steam boiler comprises a furnace body, a boiler body positioned above the furnace body and a chimney arranged on top of the boiler body; a combustion chamber is arranged in the furnace body; the cross section of the combustion chamber in the furnace body is elliptical. The hearth of a boiler in the prior art is usually square, the hearth with the structure is practical and convenient, but is poor in heat preservation effect, the square hearth can easily cause combustion dead corners and lead to insufficient combustion at the dead corners, so as to result in slag bonding at the corners, and further, the slag is difficult to clean, and the demand of industrial production cannot be met. The cross section of the combustion chamber in the furnace body is designed to be elliptical, so that the combustion chamber is free of corners and cannot generate slag and accumulate impurities easily, and moreover, temperature can be distributed more uniformly, and the production operation risk can be favorably reduced.
Description
Technical field
The utility model relates to steam boiler, particularly relates to a kind of energy-saving steam boiler.
Background technology
Boiler is a kind of energy conversion, and it is mainly by energy transform into heat energies such as the chemical energy in fuel, electric energy, and through steam or the organic heat carrier of boiler output high temperature, high pressure, the boiler that wherein produces steam is called as steam boiler.How to improve boiler structure with reach fuel combustion more fully, promote boiler thermal output, reduce the objects such as customer using cost, be that boiler design technical staff is devoted to the problem solving always.
Utility model content
The purpose of this utility model is to provide a kind of energy-saving steam boiler, and to solve, boiler furnace heat insulation effect of the prior art is poor, burnt in dead angle in easy generation simultaneously, the problem of the more difficult cleaning in combustion chamber.
The utility model energy-saving steam boiler, comprises furnace body and is positioned at the pot body of furnace body top, is provided with combustion chamber, the cross section ovalize structure of described combustion chamber in described furnace body.
In prior art, the burner hearth of boiler is generally square, although the burner hearth of this structure is practical and convenient, but heat insulation effect is poor, and square burner hearth easily produces burning dead angle, cause fuel combustion herein insufficient and then make edge easily produce slagging scorification, more difficult cleaning, can not meet industrial needs.Combustion chamber cross section in furnace body is designed to ellipse, makes like this combustion chamber without corner, be difficult for producing slagging scorification, pile up impurity, temperature can distribute more uniformly, reduces dangerous.
In order to make fuel more even in the indoor layout of boiler combustion, as the optimization of such scheme, fuel inlet that also can described combustion chamber is set to 2.
As the improvement of such scheme, can also outside furnace body, configure and spray into formula feeding screw, and the discharging opening that makes to spray into formula feeding screw be tilted to the fuel inlet of combustion chamber and be communicated with.Adopt this scheme, fuel is sent in combustion chamber to be tilted to upper type through spraying into formula feeding screw, is convenient to fuel to float short side formula suspension combustion, increases the burning area of fuel, improves the utilization rate of fuel, reduces fuel consumption.
As another improvement of the utility model scheme, the impurity producing for ease of combustion process is easy to discharge boiler, in pot body, is provided with drum, is provided with the down-comer being connected on drum in the bottom of described drum.
To sum up, the beneficial effect of the utility model steam boiler is: chamber structure, for oval, can make fuel in combustion process, be not easy to produce slagging scorification in surrounding; 2 fuel inlets are set in combustion chamber, make fuel more even in the indoor layout of boiler combustion, improve efficiency of combustion; Spray into formula feeding screw discharging opening for the upward spray of tilting, make fuel have burning area more fully, can improve efficiency of combustion; The bottom of drum is communicated with some down-comers, is conducive to grey matter, waste material to be discharged.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
The high efficiency energy-saving steam boiler stove of the present embodiment, mainly by furnace body, be positioned at the pot body of furnace body top and be located at the chimney of pot bodies top, and several parts such as combustion chamber of being located in furnace body form.As shown in the figure, in pot body, be provided with drum, in drum, lateral arrangement has top smoke pipe, middle part smoke pipe and bottom smoke pipe from top to bottom; In pot body outside, be provided with the second smoke box, in the pot body outside on the second smoke box opposite, be provided with the first smoke box and be positioned at the 3rd smoke box above the first smoke box; Combustion chamber is communicated with the first smoke box, and the first smoke box is communicated with the second smoke box by bottom smoke pipe, and the second smoke box is communicated with the 3rd smoke box by middle part smoke pipe, and the 3rd smoke box is communicated to outlet flue by top smoke pipe, and described outlet flue is communicated to chimney.
When described top smoke pipe, middle part smoke pipe, bottom smoke pipe are designed to respectively include some monomer smoke pipes, obviously more contribute to increase the area of heating surface, improve thermal conversion efficiency.
For combustion gas better, between outlet flue and chimney, can connect by installing air-introduced machine additional (figure slightly).
Embodiment 2
The main difference part of the present embodiment 2 and embodiment 1 has been to change the shape of combustion chamber 1, as shown in Figure 1, make its combustion chamber cross section ovalize structure, make like this combustion chamber 1 surrounding without corner, the impurity that fuel produces in combustion process is not easy to pile up in surrounding, makes temperature to be evenly distributed simultaneously.
Embodiment 3
The present embodiment 3 is with the main difference part of embodiment 1, is provided with drum 8 in pot body, is provided with the down-comer 15 being connected on drum in the bottom of described drum 8, makes the impurity producing in combustion process be easier to discharge.
Embodiment 4
The present embodiment is on the basis of above-described embodiment, for combustion chamber 1 is provided with 2 fuel inlets, make fuel can select according to actual needs one or simultaneously from 2 fuel inlets, enter respectively combustion chamber, fuel inlet in combustion chamber simultaneously is also provided with and sprays into formula feeding screw 9, the feeding end that sprays into formula feeding screw 9 is connected with feeding device and motor, the discharging opening 16 that sprays into formula feeding screw 9 is communicated with the fuel inlet of combustion chamber, and this discharging opening 16 is tilted to the fuel inlet of combustion chamber and is communicated with.Adopt this scheme, be convenient to make the biomass fuels such as the especially wooden chaff of fuel, straw to float short side formula suspension combustion, contribute to full combustion of fuel, reduce fuel consumption.
